Detailed explanation-1: -When an earthquake occurs, it releases energy waves, known as Seismic waves. It is like the ripples created in water if you throw a stone in it. Seismic waves are like ripples that can travel through the inside of the earth and on the surface.
Detailed explanation-2: -Seismic waves are waves that travel through or over Earth. They are usually generated by movements of the Earth’s tectonic plates (earthquakes) but may also be caused by explosions, volcanoes and landslides.
Detailed explanation-3: -Seismic waves are the waves of energy caused by the sudden breaking of rock within the earth or an explosion. Therefore, seismic waves are caused by earthquakes. It is the energy that travels through the earth and is recorded on seismographs.
Detailed explanation-4: -When an earthquake occurs, it produces shock, or seismic, waves. Two kinds of shock waves can travel through Earth’s interior: P (primary) and S (secondary). These waves travel in different ways and at different speeds. P-waves are stronger and faster than S-waves and move in a different way.
Detailed explanation-5: -Body Waves-Primary (P) & Secondary (S) Waves. Surface Waves-Rayleigh & Love Waves.
